The invention herein presents a heat xture useful for various purposesbut devised to be especially useful for warming outbuildings, such, forexample, as farm milk houses.

The heat fixture is constituted as a hollow body supporting channelmembers with which heating lamps are assembled and providing a housingfor lead wires to the heating lamps.

The object of the invention is to provide a heat xture of the characteras stated wherein will be incorporated simple, inexpensive, practical,efficient, novel and improved features of construction.

Speaking generally, the new and improved heat fixture consists of ahollow body supporting channel members with which heating lamps of saidheat xture are assembled and providing a housing for lead wires of anelectrical system in which said heating lamps are adapted to beconnected. In practical use, the hollow body oi the heat xtureordinarily will be supported upon a building structure, as from aceiling, denoted I0, such as the ceiling of a farm milk house or otheroutbuilding.

A hollow body of the heat fixture is constituted as a generallyrectilinear member consisting of spaced, parallel, first and second basewalls, indicated II and I2, respectively, spaced, parallel, oppositeSide walls I3, I3 and spaced, parallel, opposite end walls I4, I4. Theside and end walls are perpendicular to each other and to the first andsecond base walls, and all of said side, end and base walls are joinedat their locations of meeting.

The opposite side margins or the second base wall I2 terminate inequally spaced, parallel relation to the side walls I3, I3, thus toprovide rectilinear openings I5, I5 at the opposite sides of said secondbase wall between said opposite side margins and said side wallsspanning the distance between the end walls I4, It. Opposite sideportions of the second base wall extend inwardly of the hollow body andtoward each other to provide interiorly projecting, oblique boundingwalls I6, IB at the opposite sides of an interior surface I'I of saidsecond base wall.

Each of a pair of parallel channel members of the heat iixture isdesignated I8. t is to be understood, however, that a heat ixture madeaccording to the invention can include a greater or less number ofchannel members.

Each of the channel members is constituted as an elongated base I9,spaced, elongated side walls 29, 20 extending away from opposite sideedges of the elongated base, and spaced, parallel, end walls 2|, 2Icontiguous with the opposite ends, respectively, of the elongated baseE9 and the elongated side walls 29, 29. The side and end walls of eachchannel member are in perpendicular relation to each other and to theelongated base, and each channel member is open at its side opposite itselongated base save for an overhanging flange 22.

The channel members I8, I8 are situated in the hollow body of the heatxture with their elongated bases I9 and exterior portions of theirelongated side walls 20, 2D and end walls 2i, 2i disposed in or adjacentto the rectilinear openings I5, I5, and each channel member is supportedupon said hollow body for rotative movement. More explicitly stated,each of the end walls 2i of each channel member I8 is supported upon apivot element 23, disclosed as small screw bolts, situated in theadjacent end wall I4 of the hollow body, for rotative movement of thechannel members in a plane perpendicular to the rst and second basewalls II and I2. The construction and arrangement will be such thatwhile said channel members substantially lill the rectilinear openingsI5, I5 they will be free for limited rotative movement in said hollowbody. Each pivot element or screw bolt 23 has a slotted head disposed atthe exterior side of the corresponding end wall I4 and supports a springnut 2t to be engaged against the interior surface of the correspondingend wall 2l. Lugs 25, one for each spring nut, struck interiorly fromthe end walls 2l are for precluding turning movement of the spring nuts.The end walls 2l are adapted to be frictionally grasped against the endwalls I ll,

thus to preclude rotative movement of the channel members, in responseto turning home actuation of the pivot elements or screw bolts 23 aftersaid channel members have been rotatably adjusted to any positionrelative to the hollow body of the heat fixture which may bepredeterminedly selected. The construction and arrangement desirably canbe such that when the elongated bases I9 of the channel members I8 areparallel to the first base wall I I said elongated bases will lie in asingle plane substantially alined with the second base wall I2, as inFig. 6 of the drawings.

Perforations 23 through the first base wall II are for receivingfastening means 2l, screws as shown, for securing the heat fixture to aceiling, such as I0, or to some other supporting structure.

The elongated bases I9 of the channel members I8 support heating lamps28, and the interior surface Il and oblique bounding walls IB, I6 of thehollow body of the heat fixture together provide a housing for leadvwires tosaid heating lamps.

An end wall I4 of the hollow body suitably and conveniently supports aninsulating bushing 29,

disposed between and in spaced relation to the channel members I8inalined relation to the lead wire storage space provided by saidinterior surface I'I and oblique bounding walls I6, I, providing aninlet for lead wires to the interior of said hollow body. A switch formanually Vturning the electric current off and on is indicated 3l, and athermostat for-controlling .current to the heating lamps .is denoted 32.

Each of the opposite end portions of the elongated base IB of each ofthe channel members I8 detachably supports a receptacle 33 for a heatinglamp 28. The receptacles 33 ca-n be of duplicate construction and .eachcan be assembled with its corresponding elongated base in the samemanner as all of the others. ing lamp receptacle is constituted as aninsulating block 34 inside the corresponding channel member and a lampreceiving shell 49 projecting forwardly through Yan opening in thecorresponding elongated base. An insulating nut 35, threaded upon thefree end portion of an external surface .of each shell and engagedagainst the forward surface of the corresponding elongated base, retainsan annular shoulder of the corresponding insulating block in surroundingrelation to the shell .against the interior or rearward surface vof saidcorresponding elongated base, thus to cause each receptacle to be maderigid vwith the lelongated base by which supported. The insulating nuts35 are threaded upon external surfaces of the shells, and the heatinglamps 26 are threaded in internal surfaces of said shells in customarymanner.

An incoming wire 3S .from a `source (not shown) of electrical energyextends to a first fixed contact element .31 of the thermostat 32, asecond fixed contact .element of said thermostat is denoted 38, and amovable contact element l39, adapted to bridge the xedrcontact elements3l and i38, is supported by a bi-metallic strip of the thermostat.

A lead wire 4I extends from the fixed contact element 38 by way ofleadwires `42 to each of the heating lamps `28, and lead wires 43 extendfrom each of said heating lamps to an incoming wire 44. The constructionand arrangement will be suchthat the movable contact element 39 willbecome engaged with the fixed contact elements 3'I and 38 'inresponse todecrease in temperature and disengaged from said fixed As disclosed,each heatl Cil `4 contact elements in response to increase intemperature.

The manually actuable switch 3l includes a fixed Contact element 45,with which the incoming wire 36 is conductively connected by a lead Wire46, and a movable contact element 4l, conductively connected by a leadwire 48 with the lead wire 4 I.

All of the lead wires to the heating lamps 28 will be situated withinthe housing provided by the interior surface I'Iand the oblique boundingwalls I6, I6 of the hollow body of the heat xture, upon said interiorsurface, and the channel members are open to said housing across theinterior surfaces of the overhanging flanges 22, 22. Thus Jpassagewaysfor lead wires of the electrical .system to the heating lamps areprovided.

The channel members I8 of course are rotatably adjustable in the hollowbody of the heat fixture, in the manner as hereinbefore set forth, tothe end that heat from the lamps 28 can be directed toward differentvlocations of ,a room or space equipped with the .heat fixture whichvmay be selected, it being a well 4known fact that more heat emanatesdirectly forwardly from the outer end of a lamp bulb than sidewaysthereof. The heating lamps 28 are independently adjustable. In Fig. 3 ofthe drawings, the channel member at the left is at .adjusted position tocause heating lamps when supported thereby to direct their heatvertically downward from the ceiling IU, and the channel member at theright is at adjusted position to cause heating lamps .when supportedthereby to direct their heat downwardly ltoward the left. Each of thechannel members is capable of adjustment through an arc sufficient inextent to direct heat from lamps supported thereby toward distantlyspaced locations of a room -or space having the heat fixture.
